A few here have reported good results with the Gear Vendor's overdrive. Replacing the Packard rear end with a Columbia unit would seem to me to be a complicated and expensive project. Some have mentioned having special high ratio (low numerically) gear sets (ring and pinion) made. Either way, a highway cruising gear ratio will allow your engine to run slower, and be more quiet and have less wear. You may not want to go any faster. JWL
